We have Homekit enabled Airplay2 supported accessory. We are using below Homekit SDK method in our app to add/pair Airplay2 accessory with the mobile device.
open func addAndSetupAccessories(with payload: HMAccessorySetupPayload, completionHandler completion: @escaping ([HMAccessory]?, Error?) -> Void)
In IOS 15 developer beta, after adding the Airplay2 speaker accessory we are receiving HMErrorDomain error with error code: -1 and description: 'unexpected error' from Homekit SDK.
This issue doesn't observe in IOS 14 or the previous OS versions.
